Thermal comfort analysis of PMV model Prediction in Air conditioned and Naturally Ventilated Buildings

摘要

Energy saving in commercial and residential buildings have a potential with respect to improvement of thermal comfort standard. Predicted Mean Vote (PMV) model is considered to be most recognized in thermal comfort standards. Analysis of PMV model in naturally ventilated and air conditioned buildings present the percentage of under/over estimation level. PMV equation underestimates thermal sensation by 13% in summer season and overestimates by 35% in winter season, for NV buildings whereas in case of HVAC buildings overestimation is found to be 31% and 33% in the summer and winter seasons respectively. Percentage deviation of overestimation rate in HVAC buildings is higher than NV buildings.
